Discussion on 'Estimating depth-averaged velocities in rough channels'
2002
In this short communication the four estimate criteria of the depth-averaged local velocity proposed by Byrd et al. (Earth Surface Processes and Landforms, 2000, Vol. 25, pp. 167-173) are compared both with the three-point method of Bathurst and with the average velocity obtained by integrating the velocity profile (FPa2) suggested by Ferro and Pecoraro (Water Resources Research, 2000, vol. 36, pp. 2761-2770). The comparison was carried out using 84 velocity profiles measured by an acoustic Doppler velocimeter in a rectangular flume with a gravel bed. Copyright © 2002 John Wiley and Sons, Ltd.
1,4 dihidropiridinski derivati povećavaju ekspresiju gena Psma3, Psmb5 i Psmc6 u glasničkoj RNA štakora
2021
The ubiquitin-proteasome system modifies different cellular and protein functions. Its dysregulation may lead to disrupted proteostasis associated with multiple pathologies and aging. Pharmacological regulation of proteasome functions is already an important part of the treatment of several diseases. 1,4-dihydropyridine (1,4-DHP) derivatives possess different pharmacological activities, including antiaging and neuroprotective. The aim of this study was to investigate the effects of several 1,4-DHP derivatives on mRNA expression levels of proteasomal genes Psma3, Psmb5, and Psmc6 in several organs of rats. Rats were treated with metcarbatone, etcarbatone, glutapyrone, styrylcarbatone, AV-153…
Gamma-Ray-Induced Structural Transformation of GQDs towards the Improvement of Their Optical Properties, Monitoring of Selected Toxic Compounds, and …
2022
Structural modification of different carbon-based nanomaterials is often necessary to improve their morphology and optical properties, particularly the incorporation of N-atoms in graphene quantum dots (GQDs). Here, a clean, simple, one-step, and eco-friendly method for N-doping of GQDs using gamma irradiation is reported. GQDs were irradiated in the presence of the different ethylenediamine (EDA) amounts (1 g, 5 g, and 10 g) and the highest % of N was detected in the presence of 10 g. N-doped GQDs emitted strong, blue photoluminescence (PL). Photoluminescence quantum yield was increased from 1.45, as obtained for non-irradiated dots, to 7.24% for those irradiated in the presence of 1 g of …

Herbivore-Induced Changes in Cotton Modulates Reproductive Behavior in the Moth Spodoptera littoralis
2017
Plants produce chemical defense compounds to resist herbivore attack either by repelling the herbivores or attracting natural enemies of the herbivores. We have previously shown that volatile compounds from cotton released in response to herbivory by conspecifics reduce oviposition in cotton leafworm moth Spodoptera littoralis. It remained, however, unclear whether herbivore-induced changes also affect moth pre-mating and mating behaviors. In this study we examined the effect of herbivore-induced changes in cotton on reproductive behaviors i.e., female calling, male attraction and investment, and mating behavior in S. littoralis. We found a reduction in the number of females calling i.e., f…
Le coppie omoparentali e il percorso adottivo in Italia e nel Regno Unito
2022
In the past, several theories were oriented on the assumption that the adoption of children should be the prerogative of heterosexuals, preferably married couples. Now, this assumption would be considered wrong to arbitrarily exclude any particular groups of people from consideration the chosen way of life of some adults may mean that they would not be able to provide a suitable environment for the care and nurture of a child.

La ecografía Doppler con flujo en color en el diagnóstico, tratamiento y pronóstico de la Enfermedad de Graves-Basedow
2022
Introducción La ecografía Doppler tiroidea es un método no invasivo que puede proporcionar información acerca del estado funcional de la glándula tiroidea de forma indirecta mediante el estudio de la vascularización. Cada vez más autores proponen la ecografía Doppler tiroidea como primera herramienta para el diagnóstico diferencial de la tirotoxicosis. Hipótesis La ecografía Doppler tiroidea podría ser una técnica útil para establecer el diagnóstico de la Enfermedad de Graves-Basedow (EGB), planificar la dosis de antitiroideos de síntesis y establecer la probabilidad de recidiva tras finalizar el tratamiento médico. Objetivos principales Establecer el valor de la ecografía Doppler tiroidea …
Adopción en casos especiales y unidad del status filiationis en el derecho italiano: ¿cómo repercute en el plano sucesorio?
2022
In the Italian legal system, there has recently been recognition by the Constitutional Court in adoptions in particular cases of the existence of civil relations between the adoptee and the relatives of the adopter, thus equalizing the margins of protection of minors, regardless of the situations of fact or law from which the new status of the child originated. This jurisprudential work is full of considerable systematic reflections and is intended to be applied not only to the hypothesis of adoption by same-sex couples, but also to all those cases in which a state of semi-permanent abandonment or cyclical abandonment occurs. Notwithstanding the negative value directed at the forms of surro…
DEFECTS IN DOPAMINERGIC PATHWAY AFFECT CONTRACTILITY OF COLON FROM HYPOXANTHINE-GUANINE PHOSPHORIBOSYLTRANSFERASE (HPRT) KNOCKOUT MICE.
2010
Lesch-Nyhan disease is an X-linked neurobehavioral and metabolic disorder caused by lack of hypoxanthine phosphoribosyltransferase (HPRT), a housekeeping enzyme responsible for recycling purines. The mechanisms underlying the neuropathology are not well understood, but the main neurochemical defect, in central nervous system, is linked to a dysfunction of dopaminergic pathway. In the enteric nervous system the dopaminergic nerves are a subset neurons of regulating gut motility, thus we investigated possible changes in colonic motility of HPRT ¯mice related to the dopaminergic control. We evaluated, in vitro, the mechanical activity of circular muscle strips from wild type and HPRT – mouse c…
